Subject: CLUSTERS OF GALAXIES AND SUPERCLUSTERS                      
  Title: A STUDY OF MERGING IN CLUSTERS OF GALAXIES                                      


Abstract:
 We propose two x-ray bright clusters with apparently on-going mergers for detailed
 study with ASCA. With these observations, we can estimate the total mass and heavy
 element distribution of the subclusters comprising each cluster and examine
 subcluster interactions in the form of shocks which are expected to occur as the
 subclusters merge. The ASCA observations, when combined with extensive optical
 spectroscopy and ROSAT images, provide powerful tools for investigating cluster dynamics and mergers.
